8.3 Hyperlink-related location addresses

Subclauses:

The following location address forms provide queries for addressing hyperlinks and their anchors. Both forms are derived from the fundamental queryloc element form (see 7.11.1 Query location address).

8.3.1 Hyperlink location address

The element form hyperlink location address (linkloc) addresses hyperlinks by link type. The content of the linkloc is a list of zero or more GIs. The location source of the linkloc is the document or documents from which links are to be selected. If no GIs are specified, the linkloc addresses all hyperlinks in the location source documents.

NOTE 251 In effect, linkloc selects from HyTime semantic groves derived from the location source documents all nodes whose class is "hyperlink" and whose "typename" property value is equal to one of the link type names specified (see B HyTime Property Set for details).

8.3.2 Hyperlink anchor location address

The element form hyperlink anchor location address (anchloc) addresses the anchors of hyperlinks by anchor role name. The content of the anchloc is a list of zero or more anchor role names. If no anchor role names are specified, anchloc addresses all anchors of all hyperlinks in the location source.

The location source of anchloc shall be one or more documents or link elements. For documents, all links in the document are addressed.

NOTE 252 The hyperlink location address form can be used to address all links of a particular type.

NOTE 253 In effect, for each link addressed as the location source, anchloc selects the nodes in the "object" or "members" properties of the anchor or list anchor subnodes whose "rolename" property value matches the anchor role name (see B HyTime Property Set for details).
